HOSE-COUPLING.

SPEGIFICATIONforming part of Letters Patent No. 571,361, dated November 17, 1896. Application filed May 21,1896. Serial No. 592,877. (No model.)

To all whom it away concern:

Be it known that I, PIERRE ETIENNE GU1 RARD, a citizen of the Dominion of Canada, residing at Montreal, in the district of Montreal and Province of Quebec, Canada, have invented certain new and useful Improvements in Hose-Couplings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to hose-couplings; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.

In the drawings, Figure 1 is a longitudinal section through the hose-coupling with the guard-pipe broken away to show the springfingers. Fig. 2 is a cross-section taken on the line 00 ac in Fig. 1. Fig. 3 is a longitudinal section through one half of the coupling between the spring-fingers, showing the guardpipe in position.

A is the outer half of the coupling, which is provided with a cylindrical end portion at, having a shoulder for the end of one section of the hose-pipe to engage with. The front end of the part A has an internal shoulder B, a conical ring 13 of india-rubber or other soft material, and an annular groove 17 between the said ring and shoulder. The ring 13 is se cured in the partAin any approved manner.

0 is the inner half of the coupling provided with a shoulder for the other section of the hose-pipe to engage with in the usual manner. The front end of the part 0 is provided with a conical portion 0 for bearing against the ring B when the parts A and C are pressed together. The part 0 has a series of longitudinal slots D, and d is a series of springfingers having their rear ends secured to the rear end of the part 0 in any approved manner.

The fingers 01 each have two inclined projections e and e, which project through the slots D, and fis a notch between. the said projections. The outer surfaces of the projections are inclined in opposite directions, and the projections have their high ends next to the notch between them G is a ring which is slidable on the part 0 of the coupling behind the projections e. WVhen the parts of the coupling are pressed together, the projections 6 spring into the groove 1) and hold the two parts of the coupling securely connected together. lVhen the sections of the hose-pipe are to be separated, the ringG is slid upon the projections 8, so that the projections e are pressed inward until clear of the shoulder B. This permits the halves of the coupling to be separated.

A guard-pipe g is secured inside the part 0 to prevent water from passing out of the slots D.

What I claim is-= 1. In a hose-coupling, the combinatiomwith one half of the coupling provided with a shoulder at its front end and an annular groove behind the said shoulder; of the other half of the coupling provided with a series of longitudinal slots, a series of spring-fingers each having two inclined projections extending through the slots, and notches between the said projections; and a slidable ring for pressing inward the said spring-fingers, substantially as set forth.

2. In a hose-coupling, the combinatiomwith one half of the coupling provided with a conical ring of soft material, a shoulder at its front end, and an annular groove between the said shoulder and ring; of the other half 80 of the coupling provided with a conical front end for bearing against the said ring, a series of longitudinal slots, a series of spring-fingers each having two inclined projections extending through the said slots, and notches between the said projections; and a slidable ring for pressing inward the said spring-fingers simultaneously and releasing the halves of the coupling, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses,

PIERRE ETIENNE euERARn.
